Coasters after a leg injury in Theme Parks, Roller Coasters, & Donkeys! Posted September 30, 2017 I had my hip replaced at 36 a couple of years back. I took most of the next year off, but have had no trouble riding coasters since then. That said, I haven't been on anything with really extreme air time either, and I'm a little worried about hip pressure from rides like Skyrush. Best of luck with your recovery!
